Variables / Type casting
Type casting

Type casting in PHP works much as it does in C: the name of the desired type is written in parentheses before the variable which is to be cast.
<?php
$arr1 = array(1, 2, 3);
$arr2 = (string) $arr1;
var_dump($arr1);
// array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) }
var_dump($arr2);
// string(5) "Array"php.net
